whether any race of indica is also present is not known. For the 

 present, Mysore must be included within the range of malabarica, 

 but the form found there seems to diflfer quite as much from typical 

 malabarica as it does from typical hengahnsis. When more material 

 is available, it will probably (joined with the form of the Godavery 

 Valley), be separated as a quite constant geographical race. 



8. Rtxtufa gigantea, McCl. 



1839. Sciurus giganteus, McClelland (Horsfield), P. Z. S. p. 150. 



Colour. — Above, entirely black, individual hairs paling to * burnt 

 umber' at their bases; below, buff, individual hairs of the abdomen 

 however, black for their basal halves, giving a soiled appearance to 

 this part. Face coloured like back, cheeks upwards to a line drawn 

 from the ear to the nose through the eye like the belly, except for 

 a dark horizontal streak below the eye. Two small black spots below 

 the chin. 



Skull. — Longer than in macruroides. 



Dimensions. — Head and body, 417; tail, 47 7; hindfoot, 87. 

 Skull : greatest length, 80 ; basilar length, 62 ; zygomatic breadth, 

 49; nasals, 26; diastema, 17.6; braincase breadth, 35.5; inter- 

 orbital breadth, 31 ; upp'^r molar series, 15. 



Distribution, — The species was described " from seven or eight 

 specimens" taken in Assam. The Natural History Mu.'^eum has no 

 specimen from that locality, but 2 skins fnmi the N. Burma frontier 

 and one from N. Siam show no variation and accord well with 

 McClelland's description.
